[libvirt] [PATCH v2 0/8] Dump domain's IP addresses
by Michal Privoznik
It's been a while since I tried get this in. I've reworked the
patches, the exposed API, and start new round of reviews.
Moreover, during work I've come to point, where extending qemu
guest agent seemed wise:
http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg03264.html
Therefore I am introducing 'flags' field, which can contain some
boolean values we don't have yet, e.g. IFF_UP, IFF_PROMISC, etc.
Re: 'dstaddr' field in struct _virDomainInterfaceIPAddress;
It's basically a join of:
union {
char *dstaddr; /* for IFF_POINTOPOINT interface */
char *broadaddr; /* for IFF_BROADCAST interface */
}
Since an interface cannot has both flags set (see man 3
getifaddrs) I've joined both into one 'char *dstaddr'. I know it
is not mnemonic as the union, so I left it for discussion. I can
change it if you want to.
diff to v1:
-don't return array of objects, but array of pointer to objects instead
Michal Privoznik (8):

[libvirt] problem in pciFindStubDriver
by Chunyan Liu
For Xen PV guests, pciback is the only working driver, pci-stub
doesn't work. Current function finds pci-stub driver first, if
pci-stub doesn't exist, find pciback. It won't work for Xen PV guests
since it will find pci-stub driver and return, but in fact it needs
pciback.
One way is to prefer pciback rather than pci-stub like in following
patch. But that will change the behaviour of other drivers too. Is
there any preferred aprroach to handle this?

[libvirt] [PATCH] qemu: Don't parse log output when starting up a domain
by Michal Privoznik
Despite our great effort we still parsed qemu log output.
We wouldn't notice unless qemu changed the format of the
logs slightly. Anyway, now we should gather all interesting
knobs like pty paths from monitor. Moreover, since for
historical reasons the first console can be just an alias to
the first serial port, we need to check this and copy the
pty path if that's the case to the first console.

[libvirt] RFC: An "embedded" mode for QEMU/LXC drivers
by Daniel P. Berrange
This is something I was thinking about a little over the christmas
break. I've no intention of implementing this in the immediate
future, but wanted to post it while it was fresh in my mind.
Historically we have had 2 ways of using the stateful drivers like
QEMU/LXC/UML/etc.
- "system mode" - privileged libvirtd, one per host, started at boot
- "session mode" - unprivileged libvirtd, one per non-root user, autostarted
Within context of each daemon, VM name uniqueness is enforced. Operating
via the daemon means that all applications connected to libvirtd get the
same world view. This single world view is exactly what you want when
dealing with server / cloud / desktop virtualization, because it means
tools like 'virt-top', 'virt-viewer', 'virsh' can see the same VMs as
virt-manager / oVirt / OpenStack / Boxes / etc.
Recently we've seen increasing importance of a new use case which I will
refer to as "embedded" virtualization. The best example of this use case
is libguestfs which has long run a dedicated QEMU instance, but just now
switched to using libvirtd. The other use case is virt-sandbox which is
doing application confinement using LXC/KVM.
In both these cases, operating via libvirtd is sub-optimal. Users of so
called "embedded" virtualization, explicitly don't want to have interaction
with other libvirt applications. They likely don't even want to expose the
concept of virtualization to their users. For them virtualization is intended
to be just a hidden impl detail of their application.
Some issues which arise when using embedded virtualization
- Need to invent sensible unique names for each VM launched. This
leads to pollution of logfiles for QEMU instances run.
- User sees libguestfs / virt-sandbox VMs in virt-manager / oVirt
which they may then try to "manage", breaking libguestfs / etc
- Disassociated process context, so if 'virt-sandbox' is placed in
a cgroup, the VMs it launches are in a different cgroup. Likewise
if custom env variables are set, work is needed to propagate those
to VMs.
This leads me to wonder whether it is worth exploring the idea of a new
type of libvirt connection.
- "embed mode" - no libvirtd, driver runs in application context
The idea here is to take libvirtd out of the equation and directly use
the QEMU driver code in the libvirt.so client / application. Since
libvirtd (mostly) uses the same APIs as the public libvirt.so clients,
there isn't much required to make this work.
- A way for the application to invoke virStateInit for the driver
- Application must provide an event loop impl
- A way to specify alternative dirs for logs/state/config/etc
An application would access this mode using a different path for the
driver, and specifying the path to use for logs/state/config etc.
eg libguestfs might use
qemu:///embed?statedir=/tmp/libguestfsXXXXX/
to get an instance of the QEMU driver that is completely private
to itself. One question is whether there should be a single embed
instance per process, or whether an application should be allowed
to open multiple completely isolated embed instances. The latter
might require is to eliminate more static variables in our code.
This kind of embedded mode is not without its downsides though
- How to access virtual network / storage / node device APIs ?
- Extra SELinux policy work to allow each app to have the same
kind of privileges that libvirtd has to let it start VMs
- How to troubleshoot - can't use things like
'virsh qemu-monitor-command'
since the embedded instance is private to the application
in question.
One answer to the latter question, might be to actually allow the
application to expose the same RPC service as libvirtd does. So
virsh could connect to libguestfs using
qemu:///embed?socketdir=/tmp/libguestfsXXXXX/libvirt-sock
For the question of network/storage/node device access, the long
term answer is probably to split up the system libvirtd instance
into separate pieces. eg a virtnodedeviced, virtnetworkd,
virstoraged, virtqemud, virtlxcd, etc. Now a client app would
connect to their embedded QEMU instances, but to the shared
nodedevice/network/storage daemons.

[libvirt] [PATCH 0/2] Split out parts of qemu_driver.c into separate files
by Peter Krempa
qemu_driver.c is starting to grow out of proportions. This series
creates two(actualy four) files to split out some code from the main file.
1) qemu_util.c - various qemu-related tools and common code (~0.5k lines)
2) qemu_snapshot.c - snapshot related code (~1.7k lines)
Apart from reformating function headers, no changes were made to the code.
Peter Krempa (2):
qemu: Split out various utility functions to qemu_util.c
qemu: Split out snapshot related functions to qemu_snapshot.c

[libvirt] libvirtd segfault
by Scott Sullivan
### Libvirt version: ###
libvirt tagged v1.0.0 from git , with
f0e72b2f5c675f927d04545dc5095f9e5998f171 applied
### Problem: ###
Libvirtd segfaults
### Steps to reproduce: ###
This is difficult to reproduce; but appears to happen only when doing
'virsh destroys', and when they are ran in concurrent intervals, over
extended periods of time.
Here are the steps I have taken to reproduce this problem
(debian_6.0_amd64_kvm.img.gz is just a zipped up squeeze stock ISO install):
First, copy this script to ease the steps (assumed to be at
/root/libvirt_crash.pl later):
#!/usr/bin/env perl
use strict;
use warnings;
use Getopt::Long qw(:config no_ignore_case);
use String::Random;
use UUID::Random;
my ($lvms,$sleep,$restarts_per_lvm);
GetOptions(
'lvms=i' => \$lvms,
'restarts_per_lvm=i' => \$restarts_per_lvm,
'sleep=i' => \$sleep,
);
die "USAGE:\n$0 [--lvms int | --restarts_per_lvm int | --sleep int
(optional) ]\n" unless ( $lvms && $restarts_per_lvm );
sub _create_lvm {
my $opts = shift;
print "\tlvcreate -n $opts->{lvm} -L 5G /dev/LVM\n";
system("lvcreate -n $opts->{lvm} -L 5G /dev/LVM");
}
sub _kpartx_lvm {

}
my $rnd = new String::Random;
my $count = 0;
while ( $count < $lvms ) {
my $id = $rnd->randpattern("cccccccc");
print "####\nLVM PASS: $count\nLVM: $id\n####\n";

print "Shutting down LVM...\n";
_shutdown_lvm({ lvm => $id });

$restart_cnt++;
}
print "Removing LVM...\n";
_shutdown_lvm({ lvm => $id });
_remove_lvm({ lvm => $id });
$count++;
}
I then started 21 of these scripts, with the below commands (preferably
in a screen to reduce spamming):

I already had libvirtd started under GDB at this point. I waited about
3-6 hours, and I found this in my GDB session:
